To implement AWS Auto Scaling, we will create an Elastic Load Balancer (ELB), a base AMI which will be an EC2 instance running our e-commerce application, a launch configuration (the base AMI to launch in an EC2 instance), CloudWatch alarms to add/remove instances that apply to an Auto Scaling group, and finally an Auto Scaling group.
We will perform the steps in the following sections to implement auto scaling for our sample application.
